  • Proximity detector with error-preventing ambient condition compensation
    Patent number: 5367198
    Abstract: An electronic switching device such as an inductive proximity switch includes an externally influenced oscillator detector with its output connected to a switching amplifier. An electronic switch connected to the output of the switching amplifier responds to the amplifier signal and controls a state indicator. Upon the influence state of the detector crossing a predetermined threshold, the switching state of the electronic switch is reversed, and the detection state of the oscillator is reflected in switching states of the electronic switch and indicated by the state indicator. A second state indicator indicates whether or not the reading from the oscillator is in a "safe range" in which variations in ambient conditions cannot cause a false reading.
